Here's one of those signs of which way the wind is blowing. CQ is one of the insider sheets that keeps tabs and ratings on the various competitive seats around the country. They've just changed the Tennessee senate race -- where Harold Ford (D) is up against Bob Corker (R) to replace Bill Frist -- to "no clear favorite."

All the stars are going to have to be in alignment for Harold Ford to pull this off. He's got to run a kick-ass campaign, which he seems to be doing. Corker's got to run a feeble campaign. And you can check that box off. And the national tide's got to run in Harold's direction. But it may just happen.
